Abstract
A heating device comprises a heating element having a central area and a peripheral edge. The heating element has a series of slots delimiting a series of longitudinal branches connected to one another by elbows. The central area is made of a first electrically conductive material that is permeable to exhaust gases and has a first relative density. The elbows are located in the peripheral edge and are made of a second electrically conductive material and that has a second relative density greater than the first relative density.
